Technical Characteristics and Deep-Vessel Versatility
-
Flexible Cable Electrodes: The use of cables instead of rods makes the FTW32 ideal for very tall tanks or deep sumps where rigid rods would be impractical to transport or install. The cables are weighted to ensure they hang straight and provide accurate switching points.
-
Multi-Point Control: A single process connection can support up to five cable electrodes. This enables comprehensive tank management, such as setting up multiple alarm levels (High-High, High, Low, Low-Low) and automated pump control within a single device.
-
No Calibration Required: The probe is designed for immediate use. It features a standard factory setting that works with the majority of conductive liquids, eliminating the need for complex on-site commissioning.
-
Wear-Free Operation: With no moving parts, the FTW32 is not susceptible to the mechanical failures, jamming, or wear-and-tear associated with float switches. This results in an exceptionally long service life and high operational reliability.
-
Flexible Lengths: Cables can be ordered in lengths ranging from 0.25m to 15m. If necessary, the cables can be easily shortened on-site to adjust the switching points to the exact requirements of the application.

Primary Applications
-
Deep Wells and Boreholes: Monitoring water levels and controlling pumps in deep groundwater extraction sites.
-
Large Water Reservoirs: Providing multiple level alerts in municipal water storage tanks or industrial cisterns.
-
Wastewater Sumps: Detecting levels in deep lift stations or collection pits to manage pump cycles and prevent overflows.
-
Chemical Storage: Monitoring levels of conductive acids, alkalis, or salt solutions in large-scale storage vessels.
-
Overfill and Leakage Protection: Certified according to WHG standards, making it suitable as a safety limit switch to prevent environmental contamination.
